touchpad edges scrolling

Have you tried resetting the cable that goes from the trackpad to the main board ? Glad to hear that you are willing to tinker, and yes there will be replacement parts available (in the undetermined future), but even if you do get hold of a replacement part the trackpad is quite difficult to replace (see my teardown). So, in short, I wouldn't hesitate to contact support. In the meantime, do feel free to join in the IRC (see my sig) and talk about the issue with some of the more hardware savvy members.
